Find the value of X

Find the value of x

Solution

To find the value of xx, we'll use the fact that the angles around a point add up to 360360^\circ and that vertically opposite angles are equal.

Let's start by analyzing the angles:

  1. The angle (3y+10)(3y + 10)^\circ is vertically opposite the angle (9x+1)(9x + 1)^\circ. Therefore, we have: 3y+10=9x+13y + 10 = 9x + 1 Simplifying this equation: 3y9x=9(Equation 1)3y - 9x = -9 \quad \text{(Equation 1)}

  2. The angle (5y24)(5y - 24)^\circ is vertically opposite the angle 8282^\circ. Therefore: 5y24=825y - 24 = 82 Simplifying this equation: 5y=1065y = 106 y=21.2(Equation 2)y = 21.2 \quad \text{(Equation 2)}

Now that we have y=21.2y = 21.2, we can substitute this value into Equation 1 to find xx.

3(21.2)9x=93(21.2) - 9x = -9 63.69x=963.6 - 9x = -9 9x=963.6-9x = -9 - 63.6 9x=72.6-9x = -72.6 x=72.69=8.0667x = \frac{72.6}{9} = 8.0667

Thus, the value of xx is approximately 8.0678.067.
